Astronomers Detect , the Most Distant Galaxy, Ever Observed.
Astronomy.com reports that astronomers have
discovered a distant galaxy named HD1 that is now
the farthest object detected in the cosmos. .
HD1 is located approximately
13.5 billion light-years away. .
It existed , 330 million years, after the Big Bang.
Scientists believe that the distant galaxy also
contains either Population III stars or the earliest
supermassive black hole ever detected. .
Astronomy.com reports
that HD1 appears extremely
bright in ultraviolet light.
Ultraviolet is usually evidence that a galaxy is producing
a high number of stars, but the brightness of HD1 would
suggest it was creating over 100 stars every year. .
Astronomers believe, it could be the result , of one of two historic possibilities. .
Population III stars are , the first generation of stars , born following the Big Bang.
They are much more massive, luminous and hotter than stars created today, but they also have never been observed as they burn out and die quickly. .
The other explanation for the brightness of HD1 could be
the earliest known supermassive black hole, which
would beat the previous record by 500 million years. .
Forming a few hundred million years
after the Big Bang, a black hole in HD1
must have grown out of a massive
seed at an unprecedented rate. , Avi Loeb, MNRAS co-author, via Astronomy.com
